It is not visible at or south of the Equator.
Theoretically , it would appear on the horizon.
Remember the Pole Star is overhead at 90 degree N. (The North Pole). So when you have reached the Equator, your angle has changed by 90 degrees because you are now at 0(zero) degrees. So viewing the sky Polaris (Pole Star) will has now changed its angle by 90 degrees. So from being overhead, a 90 degree angle will be the horizon.
You don't see Polaris at the Equator, because of the density of the atmosphere, dust and dirt and moisture in the atmosphere.
For an observer standing on the equator, the North Star Polaris is not visible.
If it were, it would be right on the northern horizon, but from the equator, it is
probably hidden behind a tree or in the sea mist.

Some, but only the more-southerly stars. Of course, for us in the northern hemisphere, we cannot see the Southern Cross constellation of stars, either.
In the north, probably a bit under two-thirds of the way from the horizon to the zenith.

There are completely different constellations on South sky. Behind the equator there is no Northern star visible.
"Circumpolar" means the star doesn't set, and is always above the horizon.It does that if it's within (your north latitude) of the north celestial pole (roughly the North Star).At the north pole . . . your north latitude is 90 degrees. All stars within 90 degreesof the North Star are circumpolar. The North Star is directly over your head, and thewhole sky just goes round and round it. Nothing ever sets.On the equator . . . your north latitude is zero. All stars within zero of the North Star arecircumpolar. The North Star is on your horizon. Everything sets ... nothing is circumpolar.If you're reading lists of objects and their celestial (sky) coordinates in a directory or astronomicalcatalog of some kind, the number you're interested in is the star's 'declination'. That's its anglemeasured from the equator of the sky. Subtract your north latitude from 90 degrees. Then,any star with a declination more than that number is circumpolar.Example:You live near Chicago.You might live on my street, because your latitude is 42.05° north.Subtract that from 90°, get 47.95° .Anything in the sky is circumpolar if its declination is more than 47.95° .
A circumpolar staris a star that, as viewed from a given latitude on Earth, never sets.
Near the equator.
Directly overhead.

From any location north of the Equator: The north star (Polaris) is in the sky, always due north of you, and always as many degrees above the horizon as your latitude north of the equator. It makes no difference what time you look for it, or where you are in an east or west direction.
The elevation of Polaris (the North Star) above the Northern horizon is almostequal to the North latitude of the place where you are when you see it.That means that when you stand on the Equator, the North Star is exactlyON the Northern horizon, and if you stand anywhere South of the Equator,the North Star is always BELOW the horizon.But . . .Everybody in the Southern hemisphere CAN see the SOUTH pole of the sky,which nobody in the Northern hemisphere can ever see.Sadly, there's no bright star anywhere near the South pole of the sky,to mark it the way Polaris marks the sky's North pole for us.
The northern pole star "Polaris" is visible in the sky to an observer located anywhere on earth between the equator and the north pole, i.e. anywhere with a north latitude. There is no similar southern pole star.
There are completely different constellations on South sky. Behind the equator there is no Northern star visible.
-- Direction: Due north.-- Altitude above the horizon: Same angle as your latitude. Very roughly 30-45 degrees in the US.
The sky is a pinkish-red when viewed from mars because the atmosphere causes a tint.The sky would be pink when viewed from Mars.

Half. The other half is south of the celestial equator.It depends on the where you're looking from (at the equator it is half and half). If you are at latitude 30 degrees north, then about 2/3 of "your" sky is north of the celestial equator (30 degrees north means that you are one-third of the way north from the equator to the North Pole.)
The north star.
Venezuela is north the equator (technically it is incorrect to say it is above the equator. The only thing above the equator is the sky)
